tain new and useful Improvements in Liquid-Dispensers, of which thefollowing is a specification.

This invention relates to liquid dispensers.

andhas for its object to provide anappa- I ratus of this characterhaving an improved valve which is adapted to allow a prede terminedquantity of liquid to discharge each time same is operated. Theapparatus isprimarily intended to hold liquid soap to be used atwash-stands, etc., though adapted, vof course, to hold liquid flavors tobe used at soda-fountains, and the like, or for any other similarpurpose.

Further, the present invention consists of.

the novel features of construction and arrangement of parts, as Wlll behereinafter more fully described and pointed out in the claims. I

In the accompanying drawings forming part of this specification, inwhich like numbers of reference denote like parts wherever they occur.Figure 1 is a sectional View of a liquid dispenser embodying thisinvention; Fig. 2 ma sectional view on the line- 2- 2, Fig. 1, showingthe valve raised from its seat; Fig. 3 is a sectional view on the line3-3, Fig. 2; Fig. 4 is a perspective view, on an enlarged scale, of thevalve; Fig. 5 is asectional view of a liquid dispenser embodying analternate form of valve; Fig. (3 is a sectional view on the line 66,Fig. 5, showing the valve raised from its seat; Fig. 7 ism-sectionalView on the line 77, Fig. 6; Fig. 8 is a perspective view, on anenlarged scale, of the valve; Fig. 9 is a sectional view, on an enlargedscale, on the line 9-9, Fig. 8; and Fig. 10 is a perspec tive view, onan enlarged scale, ofthe guidenut.

The dispenser comprises the receptacle 1 which may be formed of glass,metal, or any other suitable material. An opening 2 in --the top of thereceptacle 1 allows the receptacle to be filled with the liquid, and ispr6 vid ed with a removable cover 8. TheQbottom of the receptacle 1contains an opening ithrough which a valve-casing 5 extends, saidopening 4 being preferably surrounded by a neck 6. The valve-casing 5 ispreferably cylindrical and is externally screwthreaded, the upper end ofsaid casing hav- .ing an internally screw-tln'eaded cap 7 fitted thereonand the lower end of said. valve casing being preferably tapered andsmooth and extending below the lower end of the neck 6. A nut 8 on thelower part of the valve-casing 5 abuts the lower end of the neck andthereby causes the flange 90011 cap 7 to press a washer 10 of rubber,leather, or any other suitable material against an annular shoulder oroffset 11 in opening 4-. with the result-of holding the valve-casing 5firmly in place in opening 4-, the washer 10, in turn, preventing theliquid from leaking out of the receptacle 1 through the openin 4:.

3L chamber 12 in the valve-casing 5 communicates at its upper end withan opening 13 in cap 7 and at its lower end with a passage 14 in thelower part of said valve casing, said chamber 12 being preferablycylindrical and larger in diameter than either the opening 18 or thepassage 14. The lower end of the wall of chamber 12 is preferablytapered in order to form a valveseat 15 against which a valve 16 isnormally held by a spring 17 said valvebeing preferably conical andhaving a valve-stem 18 which extends through the passage 14 and projectsbelow the lower end of the valvecasing 5. tially the same diameter asthe passage 14 and is provided with a cut-away portion 19 or a pluralityof such cut-away portions formed in its periphery, so'that, when thevalve 16 is raised 011' its seat 15 by pushing upwardly against thelower end 'of the valve-stem 18 with the palm of the operators hand, theliquid in the chamber 12 will not flow from said chamber into thepassage 14: until said stem has been raised suliiciently to bring theupper end of eachcut-away The valve-stem 18 has substan placed by theoutflowing liquid. As soon as pressure is released from the valve-stem18, the spring 17 returns the valve 16 and said stem to their normalposition. I

The liquid in the receptacle 1 flows through the opening 13 into thechan'iber l2. and in order to allow only the quantity of liquid withinthe chamber 12 to discharge through the passage 14: each time the valve16 is raised oh its seat 18 suiliciently to allow the liquid in chamber12 to egress through the cut-away portions 19 of stem 18, as hereinabovedescribed. the following means is provided so that the opening 13 willbe closed just previous to the opening of the passage 1 1-. valve 16extends above said valve, in alme A member 20 borne by mentwith theopening 13, and is preferably .formed cylindrical with substantially thesame diameter as the opening 13 in order to slide into and out of saidopening. For the purpose of causing the member 20 to enter readily theopening 13, said member is providedwitha projection 21 or a plural ityof such projections on its upper end, each of which projections extendsnormally into said opening. In practice it is prefer able to use amember 20 having a pair of projections 21, said projections beingpretera-bly tapered and disposed diametrically opposite each other, asdepicted in Fig. at, so that only part of'the upper ends of saidprojections engage the wall of opening 13, in order to guide member 20when same is raised with valve 16. By this arrangement a space is leftbetween the projections 21 in order to allow the chamber 12 tocommunicatc normally with the interior of the receptacle 1, thusallowing the liquid to flow from said receptacle into said chamber. Themember 20 moves upwardly with the valve 16, when the latter is raisedoff its seat 15 as hereinabove described, and when said member has beenraised sutlieiently to cause the upper edge 22 thereof to enter theopening 13, said member closes said openingjust before the cutawayportions 19 in the valve-stem 18 are raised sufiiciently to allow theliquid in said chamber to discharge through the passage 14. By thisarrangement each time the member 20 moves upwardly and closes the inletopening 13, the liquid in the receptacle 1 is thereby prevented fromflowing into the chamber 12, while the liquid in said chamber 1sdischarging through the passage 14.

After the liquid in chamber 12 has discharged through the cu't-awayportions 19 of stem 18, pressure is released from the lower end of saidstem, whereupon spring 17 causes the valve 16 to engage its seat 15 andthe member 20 to open the opening 13, with 'the result that. the airthat entered chamber 12 while the passage 14 was opened passes lieu ofcap '7 and having an opening 24' through which the member 20 is adaptedto slide. face of the guide-nut 23, as best seen in Fig. .10, so that ascrew-driver'or other suitable tool maybe inserted therein for thepurpose of turning said guide-nut. By this arrangement the guide-nut 23can be adjusted so as to increase or decrease the capacity of thechamber 12. The member 20, instead of being formed integrally with thevalve 16, .is a screw-threaded opening extending longitudinallytherethrough, so as to fit on a screw-threadedrod 26 borne by saidvalve, as best seen in Figs. 5,6, and 8. and by this arrangement isadjustable. In this form the member 20 is preferably adjustedso that theends of the projections 21 borne by same extend slightly above the upperface of guide nut and by forming the screw-threads on the rod 26 withthe same pitch as the internal screw-threads of valve-casing 5 and usinga bifurcated screw-driver, which is so constructed that its prongs willstraddle the upper end of rod 26 and will not. only seat in the grooves25 in guidenut 23, but, also, will project into the opening 24 andthereby engage" the sides of the projections 21, when the screw-driverturned,whereby said guide-nut 23 and member 20 are caused to rotatesimultancously in the same. direction. By this arrangement, when theguide-nut 23 is rotated so as to adjust same within the valvecasing 5,the member 20 accompanies a corresponding adjustment on rod 26 withoutthe relative position of said guide-nut 23 to .said member 20 beingchanged. A nut.27

fits on the upper part of valve-casing 5 in order to hold the washer 10.in engagement with the oti'set 11 in opening 4 of neck 6. The uppersurface 28 of valve 16 is slightly concave 'in order to prevent thelower end of spring 17 from slipping olt same.

While for the purpose of illustration the Grooves 25 are formed in theupper.

I necacve guide-nut 1'23 and nut 27 have been shown and described inconnection with the form of the dispenser depicted in Figs. 5 to 10, in

clusive, yet it should be understood that 5 same may be used inconnection with the form of the dispenser depicted in 1 to l, inclusive.
